Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use a high-temp self-adhering membrane wherever metal, tile or slate roofing will heat the deck beyond standard membrane limits. Apply to a clean, dry deck above 40 degrees F for best adhesion, and roll the laps firmly to seal. Keep the membrane covered by the finished roof promptly per the manufacturer's exposure limits.
Work boots and care are required on smooth self-adhered membranes; follow the manufacturer's installation instructions and local building code, and use roof fall protection.
Order the TRI-BUILT 36 in. x 65 ft high-temperature self-adhering underlayment roll for your metal or tile roof.
